php6 make install fails at filestat

Hello, The php bug site told me to send bugs to internals mailing list for HEAD compile errors, so I hope I am doing this right. I was trying to compile php6 on my system to test out a few scripts with it. I was able to configure it after I installed the ICU library with this: ./configure --prefix=/usr/local \ --with-mysql=/usr/local/mysql \ --enable-debugger I ran "make clean && make" during the "make" I received this error: /bin/sh /home/builds/tests/php6.0-200707080030/libtool --silent --preserve-dup-deps --mode=compile gcc -Iext/standard/ -I/home/builds/tests/php6.0-200707080030/ext/standard/ -DPHP_ATOM_INC -I/home/builds/tests/php6.0-200707080030/include -I/home/builds/tests/php6.0-200707080030/main -I/home/builds/tests/php6.0-200707080030 -I/usr/local/include -I/usr/local/include/libxml2 -I/home/builds/tests/php6.0-200707080030/pcrelib -I/home/builds/tests/php6.0-200707080030/ext/date/lib -I/usr/local/mysql/include -I/home/builds/tests/php6.0-200707080030/TSRM -I/home/builds/tests/php6.0-200707080030/Zend -no-cpp-precomp -I/usr/include -g -O2 -c /home/builds/tests/php6.0-200707080030/ext/standard/filestat.c -o ext/standard/filestat.lo /home/builds/tests/php6.0-200707080030/ext/standard/filestat.c: In function `php_do_chgrp': /home/builds/tests/php6.0-200707080030/ext/standard/filestat.c:440: error: `_SC_GETGR_R_SIZE_MAX' undeclared (first use in this function) /home/builds/tests/php6.0-200707080030/ext/standard/filestat.c:440: error: (Each undeclared identifier is reported only once /home/builds/tests/php6.0-200707080030/ext/standard/filestat.c:440: error: for each function it appears in.) make: *** [ext/standard/filestat.lo] Error 1 Is this a problem with the snapshot I got or an actual problem with php6?
